Luther also wrote the Large Catechism for use by pastors
and teachers.

Traditionally, all Lutherans memorized the Small Catechism,
including Luther's explanations of each of the sections.

The catechism is available in many forms from all of the
Lutheran publishing houses, though most Lutherans have agreed on a common
contemporary translation.

Many congregations use the catechism in their basic evangelism
and outreach (keeping inexpensive copies at the door for visitors) because
it provides a simple explanation of basic Lutheran teaching about God.
